Description of reference numerals: the laser protection device comprises 1-a laser protection lens, 2-a telescopic main body, 3-an elastic clamp, 4-an eyepiece connecting cylinder, 5-a main telescopic plate, 6-an auxiliary telescopic plate, 7-a rotating shaft, 8-a hinge, 9-a powerful magnet, 10-a rubber ring and 11-a clamping arm.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present invention, and should not be construed as limiting the present invention.

The embodiment of the utility model provides a: as shown in fig. 1 and 2, a laser protection device for an operating microscope eyepiece end comprises a telescopic main body 2, an elastic clamp 3 and two laser protection lenses 1, wherein two eyepiece connecting cylinders 4 are arranged on the telescopic main body 2, the two laser protection lenses 1 are respectively and fixedly installed in the two eyepiece connecting cylinders 4, the eyepiece connecting cylinders 4 are of a cylindrical structure, the two eyepiece connecting cylinders 4 are used for being connected with the microscope eyepiece, the elastic clamp 3 is arranged on one side of the telescopic main body 2, and the elastic clamp 3 is used for clamping the microscope eyepiece.

When the device is used, the upper end of the elastic clamp 3 is held, the lower end of the elastic clamp is opened, the two eyepiece connecting cylinders 4 are sleeved on the microscope eyepieces, the laser protection lens 1 is attached to the microscope eyepieces, and then the elastic clamp 3 is loosened. At the moment, the operation is carried out, an operator does not need to wear the glasses, and head discomfort or abnormal wearing caused by the size problem of the glasses is reduced. And the operator who wears the myopia glasses can avoid the inconvenience caused by wearing two pairs of glasses, thereby being more beneficial to observation and operation in the operation and reducing the risk of the operation.

The elastic clamp 3 is a main fixing device, the elastic clamp 3 can be formed by a traditional clamp structure, the structure of the clamp can refer to a clamp in the prior art, and only the clamping arm 11 of the elastic clamp 3 needs to be designed into an arc-shaped structure. The utility model discloses elasticity presss from both sides 3 and only sets up one, has reduced because of the fixed pupil distance change that brings pressure to cause microscope eyepiece end lens cone for microscope eyepiece end lens cone of binocular centre gripping.

In a specific embodiment, the telescopic body 2 comprises a main telescopic plate 5 and an auxiliary telescopic plate 6, the main telescopic plate 5 is a hollow structure, one end of the main telescopic plate 5 is provided with an opening, one end of the auxiliary telescopic plate 6 is connected with the main telescopic plate 5 in a plugging mode, and the elastic clamp 3 is installed on one side of the main telescopic plate 5 through a rotating shaft 7.

When the operator of difference uses microscope, because interpupillary distance is different, need adjust microscope, when adjusting the eyepiece width, the degree of depth in vice expansion plate 6 automatically regulated inserts main expansion plate 5 makes two eyepiece connecting cylinders 4 follow the microscope eyepiece and removes, is suitable for all people to use. In order to ensure that the eyepiece connector 4 can follow the microscope eyepiece well, a plurality of rubber rings 10 are preferably provided on the inner wall of the eyepiece connector 4. The firmness of the sleeving between the rubber ring 10 and the rubber ring can be improved.

Since many steps in the operation do not require the use of a laser, at which time the protective device needs to be removed and repeated removal and installation can affect the progress of the operation, in a preferred embodiment, the two eyepiece connector barrels 4 are mounted on the sides of the main and auxiliary

telescopic plates

5 and 6, respectively, by hinges 8. Powerful magnets 9 are arranged on the top surfaces of the main expansion plate 5 and the auxiliary expansion plate 6, and when the eyepiece connecting cylinder 4 is overturned above the main expansion plate 5 and the auxiliary expansion plate 6, the powerful magnets 9 can adsorb the hinges 8.

When the laser therapy is not needed, the protective device is not needed to be taken down, but the ocular connecting cylinder 4 is directly lifted upwards and is upturned above the ocular of the microscope. The inconvenience caused by repeatedly taking and wearing the laser goggles before and after the surgical laser treatment and the scratch damage of the lens caused in the taking and wearing process are reduced. When the eyepiece connecting tube 4 is turned over to the upper side, in order to prevent the eyepiece connecting tube from automatically turning over, a strong magnet 9 is arranged to position the eyepiece connecting tube 4.

The structure, features and effects of the present invention have been described in detail above according to the embodiment shown in the drawings, and the above description is only the preferred embodiment of the present invention, but the present invention is not limited to the implementation scope shown in the drawings, and all changes made according to the idea of the present invention or equivalent embodiments modified to the same changes should be considered within the protection scope of the present invention when not exceeding the spirit covered by the description and drawings.
